Learn by Examples How to Link the Internet of Things and the Cloud Computing Paradigms: A Fully Working Proof of Concept

This paper describes a fully-working proof of concept centered around a smart enterprise scenario and able to shed led on the power offered by linking the Internet of Things (IoT) and the Cloud Computing (CC) paradigms together. More specifically, in this showcase all the sensing and actuation capabilities are implemented in the tiny micro-controllers on-board the "things" and exposed, through a short-range radio module, as interfaces and commands, while all the smart capabilities (from identity management, to complex event processing, from data contextualization to persistent storage) are implemented as cloud services. In this way one can keep the computational and memory requirements of the devices extremely low, by off-loading the smartness of the application to the cloud services, where computational and memory resources are not an issue. Finally, to connect the two worlds together, a small linux embedded micro-pc is used as a controller, hence playing the role of a smart IoT gateway.
